Grímsvötn (Iceland): A glacial flood from the western melt water reservoir under the Vatnajökull ice cap is in progress. The Skafta River has been carrying up to 520 cubic meters per second discharge.
The water exiting the glacier door contains dissolved hydrogen sulfide from the volcano's active fumaroles under the ice. So far, only the western meltwater reservoir has been involved. The larger eastern reservoir could drastically increase the flood if it gets involved as well. In that case, the significant lowering of pressure on the volcano might increase a risk of a new eruption as well.

Karymsky (Kamchatka): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: VA IS NOT IDENTIFIABLE IN SATELLITE IMAGERY.

Suwanose-jima (Ryukyu Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 and is moving at 15 kts in NE direction.
The full report is as follows: ERUPTED AT 20210903/1153Z FL070 EXTD NE OBS VA DTG:03/1310Z to 7000 ft (2100 m)

White Island (New Zealand): (3 Sep) The GeoNet New Zealand reported that minor ash emissions have been observed by surveillance cameras starting around 06:50 local time this morning.
The activity is characterized by "only" venting of small to moderate ash from the active vent area. A satellite image from today shows an ash plume that reached the Bay of Plenty area.

Kilauea (Hawai'i): New satellite data shows that the summit of the caldera has uplifted by up as much as 18 cm during the recent earthquake swarms, which supports the interpretation that they had been caused by pulses of magma that intruded at shallow depth, thus causing the inflation of the ground above.
The inflation continues at slow rate while earthquake rates are back to normal levels, suggesting that the volcano-tectonic events have come to (at least a temporary) end.

Pagan (Mariana Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 4000 ft (1200 m) altitude or flight level 040 .
The full report is as follows: CONS EMS OBSD. to 4000 ft (1200 m)

Fuego (Guatemala): Mild explosive activity continues from the volcano. The Volcanic Ash Advisory Center (VAAC) Washington reported intermittent emissions of volcanic ash plumes.
The full report is as follows: sporadic emissions of volcanic ash

Nevado del Ruiz (Colombia): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: NEW VA EM OBSD. to 20000 ft (6100 m)

Sangay (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 20000 ft (6100 m) altitude or flight level 200 .
The full report is as follows: LKLY CONS VA EMS. to 20000 ft (6100 m)

Reventador (Ecuador): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Washington warned about a volcanic ash plume that rose up to estimated 17000 ft (5200 m) altitude or flight level 170 .
The full report is as follows: FRQT VA CLD EMS. to 17000 ft (5200 m)

Sabancaya (Peru): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Buenos Aires warned about a volcanic ash plume that rose up to estimated 27000 ft (8200 m) altitude or flight level 270 and is moving at 2 kts in VRB direction.
The full report is as follows: INTERMITTENT EMISSIONS to 27000 ft (8200 m)
